Bosch SP515 5-Piece Hex Shank Countersink Drill Bit Set | 3-in-1 Drill, Countersink & Counterbore

Overview

The Bosch SP515 5-Piece Hex Shank Countersink Drill Bit Set brings precision and versatility to your woodworking and light fabrication projects. Designed to handle wood, plastic, and composite materials, this set lets you drill a pilot hole, countersink for a flush screw head, and counterbore for screw seating in a single pass. The result is cleaner joints and fewer tool changes, helping you move smoothly from start to finish.

3-in-1 performance you can count on

With one bit and one pass, you can drill, countersink, and counterbore. This streamlined approach helps you match screw size and seating depth, creating flush setups without multiple setups or guesswork. Adjustable countersink depth adds control for different screw lengths and material densities, while the included Allen wrench makes depth changes quick and repeatable.

• Drill, countersink, and counterbore in a single operation.
• Adjustable countersink depth for precise seating without guessing.
• Hex shanks designed to reduce slippage during use.

Universal fit and compatibility

The SP515 hex shanks are compatible with most 3/8 in. and 1/2 in. corded and cordless drills, including many Bosch and competitive brands. This broad compatibility means you can use the bits with your existing kit and, in many cases, with drill presses for steady, repeatable results.

• Universal fit across Bosch and non-Bosch brands.
• Suitable for drill press use where precision matters.
• Replaceable bits available separately to extend project versatility.

Real-world use cases

Ideal for cabinetry, furniture assembly, and trim work, these bits help you achieve clean holes and flush screw heads with minimal tear-out. The design supports consistent depth control and stable bit guidance, making it a practical addition to both DIY and professional workshop setups.
